European foreword
This document (prEN 17964:2023) has been prepared by Technical Committee CEN/TC 53, Temporary
works equipment, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.

Introduction
Low height mobile working platforms with platform heights limited by design up to 2,0 m are common
on the market. Special requirements for these products are specified in this document.
The need for this document has arisen because for mobile access towers with heights from 2,50 m to
12 m were standardized in EN 1004:2004, and with the version of EN 1004-1:2020 the minimum height
was extended to 0 m. With this extension to 0 m, low height mobile working platforms would fall under
the scope of EN 1004-1. For these structures, different load assumptions and verification methods are
appropriate.
Attention is drawn to the requirements of the European Council Directive 2001/45/EC (the Temporary
Work at Height Directive).

A pre-load F of 200 N shall be applied at the midpoint of the weakest rung of any design for the duration
of one minute. The position of the rung after removal of the pre-load is the origin for measurement.
In the position of use of the low height mobile working platform a test load F of 2 600 N shall be applied
vertically on the midpoint of the weakest rung of any design evenly distributed over a width of 100 mm
and a depth equal to the rung and for the duration of one min.
Requirement:
When tested in accordance with this subclause, within two minutes after the removal of the test load
the maximum permanent deformation shall be less than or equal to 0,5 % of the inner width measured
underneath the tested rung.
12.2 Torsion test of the rungs of end frames
Procedure:
A torque M of 50 Nm shall be applied on the midpoint of the rung via a 100 mm wide clamping device.
The torque shall be applied alternately 10 times in a clockwise and 10 times in counter-clockwise
direction for a period of 10 s each.
Requirement:
When tested in accordance with this subclause, during testing there shall be no relative movement in

12.3 Side protection tests
12.3.1 Vertical loads on the side protection
Procedure:
Apply a 1,25 kN point load vertically downwards in most unfavourable position for a period of one
minute within a sector of ± 10 degrees to any principal or intermediate guardrail or any other side
protection component such as a fencing structure which has a potential foothold of 50 mm wide or
greater and regardless of its method of support. This load shall be considered as an accidental load.
Requirement:
When tested in accordance with this subclause, any principal or intermediate guardrail or any other
side protection component such as a fencing structure which has a potential foothold of 50 mm wide or
greater, and regardless of its method of support, shall be able to resist the vertically downwards point
load of 1,25 kN without detachment, cracking or rupture.
12.3.2 Horizontal load on the side protection
There are two tests for the horizontal load on the side protection:
Test 1 – Procedure:
Establish a datum as the origin for measurement of the deflection of the side protection except toe
boards regardless of their span and with reference to the supports at the points where they are
connected. Apply a 0,3 kN horizontal point load, in the most unfavourable position for a duration of one
minute, to each component of the side protection, except toe boards. This load may be distributed over
an area of 300 mm × 300 mm, e.g. when applied to the grid of a fencing structure. Measure the deflection
while the load is applied after one minute.
Test 1 – Requirement:
When tested in accordance with this subclause and while subjected to the test load, the maximum
deflection of all components of the side protection except toe boards, shall not be more than 35 mm
measured with reference to the supports at the points where they are connected.
Test 2 – Procedure:
Apply a 0,3 kN x 1,5 safety factor horizontal point load, for a duration of one minute in the most
unfavourable position and regardless of their span, to each component of the side protection except toe
-boards. This load may be distributed over an area of 300 mm × 300 mm, e.g. when applied to the grid
of a fencing structure.
Test 2 - Requirement:
When tested in accordance with this subclause all components of the side protection, except toe boards,
shall resist the load without detachment, cracking or rupture.
12.3.3 Horizontal load on the toe boards
There are two tests for the horizontal load on the toe boards:
Test 1 – Procedure:
Establish a datum as the origin for measurement of the deflection of the to-boards with reference to the
supports at the points where they are connected. Apply a 0,15 kN horizontal point load, in the most
unfavourable position for a duration of one minute, to each toe-board.
This load may be distributed over an area of 300 mm × 300 mm, e.g. when applied to the grid of a fencing
structure. Measure the deflection while the load is applied after one minute.

Test 1 – Requirement:
When tested in accordance with this subclause and while subjected to the test load, the maximum
deflection of all toe boards shall not be more than 35 mm.
Test 2 – Procedure:
Apply a 0,3 kN x 1,5 safety factor horizontal point load, for a duration of one minute in the most
unfavourable position and regardless of their span, to each toe board. This load may be distributed over
an area of 300 mm × 300 mm, e.g. when applied to the grid of a fencing structure.
Test 2 – Requirement:
When tested in accordance with this subclause any toe board shall resist the load without detachment,
cracking or rupture.
12.4 Platform deflection test
Procedure:
With the low height mobile working platform positioned as in use, a pre-load F of 200 N shall be applied
at the test location, as shown in Figure 2, for the duration of one minute. The position of the platform
after removal of the pre-load is the origin for measurement.
A test load L of 1,0 kN concentrated on an area of 200 mm × 200 mm in the most unfavourable position
on the platform (see Figure 2).
A test load L of 1,5 kN concentrated on an area of 500 mm × 500 mm in the most unfavourable position
on the platform. If the width of the platform unit is less than 500 mm, the load shall not be reduced.
